The paper describes a design of the electromagnetic mill, its technological structure and control system. Electromagnetic mill is a fully automated system, which affects the effectiveness of its operation. It is also important how the process is being conducted. Efficient raw material processing requires constant research to improve efficiency of work in both individual devices and the technological system as a whole. The key role played by new technologies is to diminish the grain size of the feed (raw material), which allows achieving significant energy savings and, at the same time, intensifying the course of the process itself. One example of such an innovation is electromagnetic mill, which in industrial applications can be used to:    • mixing of bulk materials,  • activation of the substance substrate surface  • changes in physical and chemical properties of the substance,  • acceleration of chemical reactions,  • mixing of liquids and gases,  • receiving new materials in the mechanical–chemical synthesis,  • grinding and activation of dry fly ash and desulphurisation products,  • grinding and activation of ashes with additional coals grinding,  • production of stable emulsions,  • ultra fine materials grinding,  • grinding of materials in liquid environment.    Paper development was funded within the project: PBS3/B3/28/2015
